LVII. He died in the thirty-second year of his age [637], upon the same day on which he had formerly put Octavia to death; and the public joy was so great upon the occasion, that the common people ran about the city with caps upon their heads. Some, however, were not wanting, who for a long time decked his tomb with spring and summer flowers. Sometimes they placed his image upon the rostra, dressed in robes of state; at another, they published proclamations in his name, as if he were still alive, and would shortly return to Rome, and take vengeance on all his enemies. Vologesus, king of the Parthians, when he sent ambassadors to the senate to renew his alliance with the Roman people, earnestly requested that due honour should be paid to the memory of Nero; and, to conclude, when, twenty years afterwards, at which time I was a young man [638], some person of obscure birth gave himself out for Nero, that name secured him so favourable a reception (382) from the Parthians, that he was very zealously supported, and it was with much difficulty that they were prevailed upon to give him up. * * * * * * * Though no law had ever passed for regulating the transmission of the imperial power, yet the design of conveying it by lineal descent was implied in the practice of adoption. By the rule of hereditary succession, Britannicus, the son of Claudius, was the natural heir to the throne; but he was supplanted by the artifices of his stepmother, who had the address to procure it for her own son, Nero. From the time of Augustus it had been the custom of each of the new sovereigns to commence his reign in such a manner as tended to acquire popularity, however much they all afterwards degenerated from those specious beginnings. Whether this proceeded entirely from policy, or that nature was not yet vitiated by the intoxication of uncontrolled power, is uncertain; but such were the excesses into which they afterwards plunged, that we can scarcely exempt any of them, except, perhaps, Claudius, from the imputation of great original depravity. The vicious temper of Tiberius was known to his own mother, Livia; that of Caligula had been obvious to those about him from his infancy; Claudius seems to have had naturally a stronger tendency to weakness than to vice; but the inherent wickedness of Nero was discovered at an early period by his preceptor, Seneca. Yet even this emperor commenced his reign in a manner which procured him approbation. Of all the Roman emperors who had hitherto reigned, he seems to have been most corrupted by profligate favourites, who flattered his follies and vices, to promote their own aggrandisement. In the number of these was Tigellinus, who met at last with the fate which he had so amply merited.
